I checked my drains for the cowl, there is one on each outside edge near the fender. They have a pretty large hole with a tube that goes down and drains on the back side of the fender behind the innerfender. Mine had leaves and debri in them but they were still draining, cleaned them out and flushed them. I removed the screws along the front of the cowl and could pick it up enough to gain access to clean them out. Like I said mine were not plugged so I don't think it was an issue but it feels better knowing they are clean, at least for the time being... I took some pictures to try and show the exact location of them
